This reverts commit 277559b4.

Fixes #309

This was problematic when OpenMP was used in the Elemwise outer loop

We add one extra output flag stating whether iteration converged or not. This however breaks Hyp2F1 grad in python mode because it goes beyond the Elemwise limit on number of operands. To fix it we split the grad when on python mode

It doesn't matter because we are ignoring E501

Otherwise the version comes up as "untagged" and the sdist can't be uploaded to PyPI.

Indexing vector inputs to create taps during scan, yields numeric variables which must be wrapped again into scalar arrays before passing into the inernal function.

This commit pre-allocates such arrays and reuses them during looping.
